How to solve this problem

This problem cannot be "solved" in the sense of finding a value for each variable. Please be more specific about what it is you're trying to accomplish, i.e. how to simplify, how to rewrite with all positive exponents, how to expand, etc.

Hi Regina,
 
How to solve this problem
(4ab-5)-2
 
 
 
My guess is that you want this simplified into all positive exponents.
 
 
4-2a-2b-5(-2)
4-2a-2b10
 
 
b10
--------
42a2
 
 
b10
--------
16a2
 
 
Now the expression is written simplified with all positive exponents.
 
Hope this helps you..
